Struct Version 

pub struct Version(/* private fields */);

The transaction version.

Currently, as specified by BIP-0068 and BIP-0431, version 1, 2, and 3 are considered standard.

Standardness of the inner u32 is not an invariant because you are free to create transactions of any version, transactions with non-standard version numbers will not be relayed by the Bitcoin network.

Implementations

impl Version

pub const ONE: Self

The original Bitcoin transaction version (pre-BIP-0068).

pub const TWO: Self

The second Bitcoin transaction version (post-BIP-0068).

pub const THREE: Self

The third Bitcoin transaction version (post-BIP-0431).

pub const fn maybe_non_standard(version: u32) -> Self

Constructs a potentially non-standard transaction version.

This can accept both standard and non-standard versions.

pub const fn to_u32(self) -> u32

Returns the inner u32 value of this Version.

pub const fn is_standard(self) -> bool

Returns true if this transaction version number is considered standard.

The behavior of this method matches whatever Bitcoin Core considers standard at the time of the release and may change in future versions to accommodate new standard versions. As of Bitcoin Core 28.0 (release notes), versions 1, 2, and 3 are considered standard.

fn from(version: Version) -> Self

Converts to this type from the input type.

where H: Hasher, Self: Sized,

impl LowerHex for Version

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Octal for Version

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl PartialEq for Version

fn eq(&self, other: &Version) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
